burner embodying my invention, an oil inlet pipe being shownfragmentarily.

Fig. 2 is an enlar ed longitudinal sectionthrough the burner,illustrating the efie'ct on fuel of the novel construction.

Fig. 3 is a section on the line 33, Fig. 2. Referring in detail to thedrawing: 1 designates a casing or hollow body pref erably cylindrical incross section and curved longitudinally to provide an open air inlet end2 having an axis adapted to extend horizontally, and a slightly upturnedopen outa let end 3. The casing curves downwardly from the inlet end andthen upwardly tov form the outlet, thus providing depressed upper andlower Wall portions at points des' ignated 4 and 5 substantiallymidwayof the casing. Feet 6 and 7 comprising transverse wall-like bosses areformed on the casing for supporting the same in a predeterminedpositlon'for a purpose presently disclosed. I The casing is providedwith a side inlet 8 adjacent the top portion thereof, and spacedsubstantially from the edge of the open end 2, and a transverse plate ortrough 9 having ends sealingly fixed to the sides of the casing to forma channel or chamber 10 is curved to form a trough-like shallow recessportion 11 to receive Oll from the inlet. The front end edge portion 12of the plate is flat, and extends toward the air inlet in a planesubstantially tangential to the oil inlet, thus forming one edge of amouth through which air may pass fromthe casing inlet through thechamber 10. v

The front edge 13 of the trough is slightly lower than the portion 12,to cause oil to tion thereo flow for war dl from the trough, andsaidedge is curve into oval form, whereby oil. moving from the trough willflow over the surface of said edge to the curved lower face of thetrough, and drip from the lowest p01- asindicated at 14. Located belowthe trough and inclined downwardly and forwardly is a plate 16 havingends sealingly attached to the casing,

and extending a substantial distance foran wardly from the trough.Therear edge of the plate 16 is located sufliciently rearward ofthepoint l ltoassure reception-of dripping-oil by the plate, and the'frontedge extends substantially to the 'space in the case5 ing defined by thedepressed upper wall portion 4. i

The delivery edge 17 of the plate 16 is formed oval to conduct oil tothe lower marginofsaid edge for dripping, therefrom.

A second transverse plate 18 inclined longitudinally of thecasingvoppositely tothe inclination of the plate 16 has a front edge alocated slightly ahead of the front edge of the plate 16 and slightlybelow the extended plane of the lower face of said plate, to receive oildripping from the plate 16 and conduct the oil rearwardly in the casing.The rear edge of the plate 18 has the oval formation. '80

A final member 19 of the series of inclined plates is inclinedoppositely to the vertical ly adjacent plate 18, and has a front edgelocated substantially adjacent the point 5 representing the lowest placein the bottom wall portion of the casing. I

Farmed in the rear edge portion of. the plate 19 and spaced rearwardlyfrom the rear edge of the plate 18, is a transverse recess 20 forming atrough or well. into which oil flowing fromthe plate 18 may pass, and awick 21 consisting of asbestos f or. like absorbent material, preferablyresistant to heat, is mounted in the recess to receive and hold oil andprovide convenient means for initially igniting the fuelr Air has accessto-the casingthrough the air inlet end 2 for supporting combustion ofthe oil,and air will pass freely through j the several-passages'defined'by the trough a and plates.

In order to control the airjsupply, I provide a damper includingtriangular leaves or vanes 23, 24 and 25 having inner ends mounted on abolt 26 supported on the arisof the air inlet by an ear 27 extendingfronr the casing. A spring 28 mounted onthe bolt bears againstthe nut 29thereon to urge the bolt head 30 into engagement with the leaves,whereby ally latched to the ear 27 and may be moved rotatively to anydesired positions to form and adjust the sizes and POSltlOllS ofairadmitting apertures in the ,air 1n1et end of the casing.

The outer ends of the vanes ,bear against and slide over a shoulder 32formed in the' inlet end of the casing.

A valved "oil supply pipe 33 may be threaded inthe oil inlet of thecasing for delivering fuel to the burner.

In using the-device, the legs 6 and 7 support the casing in such aposition as to maintain the trough and plates horlzontal and preventlateral tipping of the caslng, thus enabling the I livery edges of thetrough and plates.

Oil delivered through the oil inlet Wlll collect in the recess of thetrough, and flow therefrom to drip from the lower face thereof to theplate 16. P a r Attention is called to the communlcating relationbetween the trough chamber 10 and air inlet, whereby air is constantlysupplled to the oil in the trough, and formatlonof carbon therein isthus avoided.

' The oil will flow forwardly over the plate 16, and drip thence to theplate 18, to flow rearwardly in the casing and pass vto the plate 19.

Upon initially setting up flow of fuel, oil passlng to the plate l9willtend to splash to the wick,'and provide a body of oil that may beignited to suitably heat the plates and set up vaporization of the fuel.

A fine mistor thick vapor will rise from each of the plates while theoil is flowing, which will be driven'by the draft created by air movingfrom'the air inlet through the several compartments into the flameformed 1 at the front edges of the plates by the burnvapors. j 7 7 hetubular casing curved as shown and provided with longitudinally inclinedplates forming passages. at the inlet end thereof, thus provides acombustion chamber portion adjacent the upturned outlet;

The damper vanes may be adjusted to provide a desired opening or groupof openings for controlling inlet of air to" the several passages, andareadapted to. admit air to the upperpassage or trough chamber 10 whenany combustion supporting air is passin in-. to the casing, due to thespacing of the ront the vanes are frictionoil to flow evenly over thedeedge projectin edges of the plates from the air inlet end of thecasing.

What I claim and desire to secure by Letters Patent is:

' 1. An oil burner including a casing having open inlet and dischargeends, an adjustable damper at said inlet end, an oil inlet in thecasing, an upper arcuate transverse plate in said casing forming atrough in 'receivingrelation wlth the oil inlet and having a roundeddelivery edge tapering gradually into the lower surface of said arcuateplate to effect discharge of oil from the lowermost portion of theplate, a second forwardly declined plate for receiving oil dripping fromthe upper plate and having a third forwardly inclined plate projectinginto the casing beyond the front edge of the secondplate for receivingoil therefrom, and a lower forwardly declined plate extending into thecasing beyond the front edge of the third plateand receiving oildripping from the rear edge of the third plate, eac of said plateshaving unobstructedcommunication with said discharge end. 7 Q 2. .An oilburner including a casing having open inlet and discharge ends, an oilinlet in the casing, an upper arcuate transverse plate in saidcasing-formin a trough in receiving relation with the 011 inlet, asecond forwardly declined plate for receiving oil drlpping from theupper plate and located in the casing forwardly of the upper plate, a

third forwardly inclined plate located in the casing below and-forwardlyof the second plate for receiving oil therefrom, a lower forwardlydeclined plate located in the casing below and forwardly of the thirdplate and having a rdcess and a wick in the recess in substantiallyreceiving relation with the rear edge of the third plate, and'anadjustable damper at said inlet end of the eas- 1ng.

,3 An oil burner including a casing hav ing open inlet and dischargeends, an oil inlet in the casing, an upper plate havinga transversedepression-intermediate its front and rear edges to form a trough inreceiving relation with said oil inlet'and having a rounded front edgeat a lower level than the rear .edgeand tapering gradually into thelower surface of said depression to effect discharge of oil from thelowermost portion of the plate, anda second forwardly inclined plate forreceiving oil dripping from the upper plate and having a front into thecasing beyond the front edge of t e upper late. 4

.In testimony whereof afiix mv si nature.
